CARPENTERS PLANE.

Application filed May 16, 1924. Serial No. 713,664..

To all whom it may concern.

Be it known that I, lVLADYsLAw. MUoHA,

a citizen of the United States of America,

residing at New York city, Bronx County, State of New York, have invented certain new and useful Improvements in Carpenters Planes, of which the following is a specification.

This invention relates to wood Working planes, and in particular to a type adapted to be used on moldings and flooring.

A particular object of the invention is to provide planes of this type having intelchangeable handles, that is a handle that may be used on either side of the plane, and one which can be readily detached therefrom.

A further object of the invention is to provide a means for securely locking the cutting blade of the plane, in position, the means being so arranged that they can be readily operated from one side of the plane when it is desired to change or sharpen the blade.

A further object of the invention is to provide a plane having an edge guide which may be disposed on either side of the plane.

Referring to the drawing. wherein I have showed a preferred embodiment of my in vention,

Fig. 1 is a View in perspective of a plane constructed in accordance with my ideas, the handle thereof being omitted,

Fig. 2 is a partial view of Fig. 1, the same being shown in cross section to illustrate the means for holding the cutting blade in place,

Fig. 3 is a cross section in elevation, taken through one of the handle and guide retaining openings.

Fig. 4: is a bottom plan view of a plane constructed in accordance with my ideas.

Referring to the drawing in detail 5 indicates the body of a plane, which is usually constructed of hard wood bound on either side by the metallic plates 6.

The particular type of plane shown is a molding plane, and the same is of the flat type, having a blade passing therethrough, which protrudes beyond one of the narrow sides of the plane, so that the same can be used flatwise against the edge ofmolding or flooring to properly trim the same.

In my improvement, I provide for a handle which can be used on either side of the plane, the handle 7 being provided with end screws 8, the heads of which are spaced slightly from the bottom of the handles, so that the same may be inserted into the large end 9 of openings 10, the constricted portions of the openings being adapted to fit between the handle and the screw head. It will of course be understood that the wood filling of the plane is hollowed out beneath the openings, so that the head of the screw may be inserted therein, screw is of such a diameter as to have a forced fit in the constricted portion of the openings whereby the handle will be securely held in position on either side of the plane, it being understood that both sides of the plane have lock openings 10 for the reception of the handle.

In order to use the plane in connection with flooring, where the flooring is fitted together through the medium of a tongue and groove connection, I may provide the bottom edge of the plane with a flange 11 and also I may provide the sides of the plane with removable guides, only one of which is used. The guide 12 as shown being positioned on one side of the plane and its connection with the sides of the plane is made the same as the handle, that is the screw heads 13 enter the openings 14 to be securely held in restricted portions 15 thereof. 7

The cutting blade of the plane is held in position by a retaining plate 16, the face of which may be knurled as at 17 to bite into the face of the blade 18. The face of the blade may also be suitably knurled, if desired. The retainer 16 is pivotally secured as at 19 to the body of the plane and is locked in position by the locking lever 20 which is provided with an extended foot The i portion 21 which acts as a wedge when the locking lever is forced downwardly into position; the raising of the locking lever to the position shown in the dot and dash lines of course releases the plate 16 and allows the removal of the blade 18 for sharpening or other purposes.

It will be seen therefore that my invention may be applied to any particular type of plane and I do not wish to be limited to the showing on a molding or like plane. Also in operating upon diiferent kinds of molding or flooring, the handle may be changed from side to side of the plane with a minimum of time and also the blade of the plane may be quickly removed.

Thus it will be seen that I have done away withtlle; common wondiwediges as used in planes and have provided a blade looking device which is quickly and efficiently operated. Also I have provided asideedge guide which may be used on either side of the plane depending of course upon which side the handle is used.

It will be noted also that the foot portion 21 of the locking lever 20, which is pivotally mounted in the body of the plane as at 22', is pointed to engage the retaining plate- 1 6, the point being offset from the center line of the pivot 22' as shown by the dot and dash line 23 Thisv will cause the locking; lever to. snap into closed position.

Having described my invention what I olaiimi is:

A plane comprising a body portion having an opening therein, a locking lever pivoted in! said opening to the body portion and having an offset r'oot portion adjacent said pivot point, a retainer pivoted in the body portion, having knurled surfaces thereon; a blade engaged by said retainer, the foot portion of the locking lever being adapted to engage the retainer to lock the bladein position, andthe point of engagement of said foot portion with said retainer being below the pivot point of said locking lever.
